In simple terms, by making a house or commercial building as air-tight as comfortably possible, less fuel is needed to heat it. Not only does this reduce fuel bills. It also means that CO2 emissions are lower and the carbon footprint for that building is reduced.

No building will ever be totally air-tight of course, as the occupants are continually opening and closing windows and doors. There are, however, certain aspects of a building’s construction where air can escape through gaps and cracks in various parts of the building.

At Greenovation, we work alongside Cheshire builders and can identify the common (and less common!) causes of air leakage, or ‘air permeability’. In many cases, however, air leakage – as opposed to natural ventilation – is not always visible. Our air testing methods enable us to identify the full range of reasons why a property falls short in providing the optimum level of air-tightness.
